CHARLES S. RAIA, OF GARFIELD, NEW JERSEY.

ICE-CREAM CUTTER.

Application filed February 11, 1920. Serial No. 357,804.

To all whom it may concern: 7

Be it known that I, CHARLES S. RAIA, a citizen of the United States,residing at Garfield, in the county of Bergen and State of New Jersey,have invented certain new and useful Improvements in Ice-Cream Cutters,of which the following is a specification.

This invention has relation to a cutting machine, and has for an objectto provide a machine designed particularly to sever a block of ice creaminto a large number of portions, in an effective and expeditious manner.

Another objectof the invention is to provide a machine of the characterabove set forth including a plurality of vertically movable knivesdesigned to cut the ice cream, and means for heating said knives wherebythey may accomplish their work more effectively.

In addition to the foregoing this invention comprehends improvements inthe details of construction and arrangement of parts, to be hereinafterdescribed and particularly set forth in the appended claims.

In the accompanying drawings in which similar and corresponding partsare designated by the same characters of reference throughout theseveral views in which they appear:

Figure 1 is a view in front elevation of a machine constructed inaccordance with my invention.

Fig. 2 is a vertical section thereof.

Fig. 3 is a transverse horizontal section.

With reference to the drawings, 10 indicates a table upon which a rectanular openwork frame 11 is mounted. Depending from within the frame 11 isa bracket 12 supporting a frame 13 from which a plurality of heaters 14;depends, each heater being rectangular and hollow and preferably havingtheir lower edges beveled inwardly as at 15. The heaters 14 may be ofmetal, and I provide a heating means consisting of a pipe 16 extendingcentrally of the frame 13 and provided with a plurality of lateralbranches 17 which are perforated and extend into the boxes 14. The pipe16 is designed to be attached to a source of gas supply which may beignited at the openings of the extension 17 the flame acting to heat thesides of the heater.

The table 10 is provided with a pair of openings through which extendthe vertical members 18 of a frame work, said members carrying at theirupper end a rectangular casing 19 which is formed with a ledge 20 at itslower end. Located within the frame are a plurality of longitudinallyextending blades 21, and transversely extending blades 22 arranged atright angles. Each blade is slotted as at 23 so that the blades of oneset may be received within the blades of the other and vice versa. Theend of each blade is also reduced in width as at 24 so as to rest uponthe ledge 20, and strips 25 are then located within the upper end of theframe to seat within the recess or reduced portions of the blade tosecure the latter in place. Opposite sides of the frame 19 are formedwith dove tailed slots 26 in which dove tails 27 formed upon plates 28are received, said plates being secured to the inner faces of the framemembers 18. The frame 18 is provided with a cross piece 29 the ends ofwhich are extended beyond the frame and have springs 30 connectedthereto, the other ends of said springs being connected to the table soas to normally retain the frame in an upward position. Guide rod 31extending from the table and entering openings in the ends of the strip29 are also provided to guide the member 18. A foot lever 32 is pivotedat the lower end of the frame and. is connected to the frame 18 so as tomove the latter downward when the lever is stepped upon.

In use a block of ice cream or the like is placed upon the upper side ofthe table 10 beneath the frame 19 and the latter is moved downward inthe manner described above whereupon the block of ice cream is dividedinto a plurality of portions. It will be apparent that while the knifecasing is in an elevated position it becomes heated by radiation fromthe heaters 14% and the heated knives thus sever the ice cream morereadily and insure the separation of the portions of ice cream from theknives so that the knife blades can be readily withdrawn again. It willbe apparent that I may heat the heaters 14 by electricity instead ofgas. Other variations may be readily made in the structure hereindescribed.

While I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts without departing from the spirit ofthe invention or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by United States Letters Patent is:

1. A cutting machine comprising a table,

a rectangular frame arranged thereover for vertical movement, aplurality of blades carried within the frame arranged at rightangles anddefining compartments therebetween, a heater comprising a plurality ofrectangular members designed to enter said com partnicnts, springs forurging the frame upward, and a positive means for moving the samedownward.

2. A cutting machine comprising a table, a frame mounted thereover forvertical movement, a plurality of blades arranged within the frame atrelative rightangles defining compartments therebetween, a bracketmounted above the frame, a plurality of hollow rectangular heatersmounted in spaced relation depending from the bracket to enter thecompartments when the frame is elevated, means for heating saidrectangular heaters, springs for urging the frame upward, and a positivemeans for moving the frame downward.

In testimony whereof I afiii; my signature.
